Stopwatch
The 1/1000-second stopwatch measures elapsed time, as well as lap/split times, and
has an Auto-Start feature. Measurements taken using the stopwatch can
be stored in memory for later recall with the Recall Mode.
• “Lap time” is the time spent to cover a specific segment of a race, such as one lap
around a track. “Split time” is the time spent from the beginning of a race up to a
certain point.
• For information about how data recorded with the stopwatch is stored in memory,
see “Memory Management”.
• The stopwatch measurement operation continues even if you exit the Stopwatch
Mode.
• The stopwatch continues to run, restarting from zero after it reaches its limit, until
you stop it.
• All of the operations in this section are performed in the Stopwatch Mode, which you
enter by pressing C.
• While the stopwatch is stopped and reset to all zeros, you can press B to switch
between the elapsed time and lap time screens.

Use the following procedure to perform a basic elapsed time operation with the
stopwatch.
To measure elapsed time
1. While the stopwatch is stopped and reset to all zeros,
press B to display the Elapsed Time screen.
• If the stopwatch is not reset to all zeros, stop the
stopwatch and then press B to reset to all zeros.
2. Press D to start the stopwatch elapsed time operation.
3. Press D to stop the elapsed time operation.
• You can restart the elapsed time operation by pressing
D again.
• After stopping the elapsed time operation, press B to
reset to all zeros.

Measuring Split Times and Lap Times
You can use the stopwatch Elapsed Time screen or the Lap Time screen to measure
split times and lap times.
• The Elapsed Time screen is recommended when you want to view the elapsed time
during split/lap time readings.
• The Lap Time screen is recommended when you want to view the current lap time
during split/lap time readings.
To take split time and lap time readings
1. While the stopwatch is stopped and reset to all zeros,
press B to toggle between the Elapsed Time screen
and Lap Time screen.
• If the stopwatch is not reset to all zeros, stop the
stopwatch and then press B to reset to all zeros.
2. Press D to start the stopwatch elapsed time operation.
3. Press B when you want to take a lap and split time
reading.
• Each press of B will display the lap/split time at that
point. You can take up to 999 lap/split readings during
a single elapsed time operation.
4. Press D when you want to stop the elapsed time
operation.
• You can press D to re-start the stopwatch elapsed time
operation, if you want.
• The watch’s memory can store up to 99 lap times. If you stop an elapsed time
operation during which you recorded more than 99 lap times, any lap times past Lap
99 will not be stored in watch memory. If you restart the elapsed time operation in
this case, the display will show --'--''--- for the last lap time until you record then
next lap time.
• After stopping the elapsed time operation, press B to reset to all zeros.
• One-digit lap numbers (1 to 9) are displayed using the format “LAP 1”.
Example: Lap time number 8: LAP 8
Two- and three-digit lap numbers (10 to 999) are displayed using the format “L.100”
or “L.50”.
Example: Lap time number 150: L.150
About Auto-Start
With Auto-Start, the watch performs a 5-second countdown, and the elapsed time
operation starts automatically when the countdown reaches zero. Beeper and flash
alert operations are performed for each of the final four seconds of the countdown.
• When the end of the countdown is reached, a beeper operation is performed
followed by a flash alert operation. The alerts are performed separately to avoid
putting too much load on the battery at the same time.
• When Flash Alert is turned on, the red and green LEDs at the bottom of the display
will flash in time with the Auto-Start countdown beeper.
To use Auto-Start
1. While the stopwatch screen is showing all zeros in the
Stopwatch Mode, press A.
• This displays a 5-second countdown screen.
• To return to the all zeros screen, press A again.
2. Press D to start the countdown.
• A stopwatch elapsed time operation will start
automatically when the end of the countdown is
reached.
• To terminate an ongoing countdown and start the elapsed time operation, press D.
• To cancel an ongoing countdown and return to the 5-second countdown screen,
press B.
Memory Management
Your watch has memory for two “elapsed time records”. Each elapsed time record
contains the data (elapsed time, lap times, split times, etc.) recorded from the
beginning to the end of an elapsed time measurement.
While an elapsed time operation is in progress in the Stopwatch Mode, the two
elapsed time records in memory are one for the data being produced by the elapsed
time operation you are performing and one for the data produced by the last elapsed
time operation you completed.
When there is no elapsed time operation in progress in the Stopwatch Mode (when
the stopwatch is reset to all zeros), the two elapsed time records in memory consist of
one for the data produced by the last elapsed time operation you completed and one
more record for the elapsed time operation before the last one.
• Whenever you start a new elapsed time operation, the older record currently in
memory is deleted automatically to make room for the new elapsed time data.
• You can use the Recall Mode to view the elapsed time records that currently are in
the watch’s memory.
Elapsed Time Record Data
Each elapsed time record contains the following data.
Total elapsed time
Up to 99 lap/split time records
Start date (month, day) and time of elapsed time measurement
Best lap time and number record
• Each elapsed time record can contain up to 99 lap/split times. The watch will not
store any more lap/split times after the 99th, but the best lap record will continue to
be updated whenever a new lap time betters the time of the current best lap record.
• If there are multiple lap times in an elapsed time record that are the same as the
time of the best lap, the earliest time is used as the best lap time.
• -- is shown for the best lap time if no lap/split time operation was performed during
the elapsed time operation.
